Hello,

The mechanism used by “guix pull” has changed. These errors no longer happen with the new mechanism. > # guix gc -R $(readlink -f ~/.config/guix/latest) ~/.config/guix/latest is no longer used. Instead “guix pull” installs a full self-contained Guix to ~/.config/guix/current/bin/. If you don’t have this you are likely upgrading from an old version of Guix before that change was made. In that case you need to upgrade to a version of Guix that has a guile-gcrypt package, then install it, and only then run “guix pull”. With the new mechanism you can simply use any of the older variants of Guix you have in ~/.config/guix/current-n-link/bin. Hope this helps! -- Ricardo
